To all whom 'it may concern:

Be it known that I, Josevi-i Scnncirrnn, a citizen of the United States, residing at New York, in the county ot New York and State of New York, have invented certain new and useful Improvements in Combination-Locks; and I do hereby declare the following to be a full, clear, and eXact description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in combination locks, and it consists in the parts and combination of parts as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of my improved lock. Fig. 2 is a view in longitudinal section showing the spindle locked. Fig. 3 is a similar view showing the locking pins in line with the gates in the tumblers and dial. Fig. L is a view of the spindle, sleeve and locking pins. Fig. 5 is a view in transverse section and Fig. 6 is a view in perspective of one of the tumblers.

1 represents the cylinder or casing which carries the entire mechanism ot the lock. This cylinder is open at its front end and provided with a flange 2, which overlaps the door around the opening therein in which the cylinder 1 is seated, and is also provided at its rear end with a small centrally located opening through which the threaded end of sleeve 3 passes.

Mounted in the open front end of the cyl inder 1, is the dial 4, having a series of notches and numbers on its edge or periphery. The rear end ot this dial is cylindrical in shape to snugly tit within the cylindrical bore of the casing 1, and is provided at its rear end with the locking pin gating 5, and with a rearwardly projecting driving pin 6, which latter is designed to engage a forwardly projecting driving pin GfL on the tumbler 7, and the latter is provided with a rearwardly projecting driving pin S, adapted to contact with a forwardly proj ecting driving pin 8a on the tumbler 9.

The tuinblers 7 and 9 are ring shaped in form, and each is provided on its inner surface with a gating 10, and each is also provided with a series of threaded holes 11 into any one of which the forwardly and rearwardly projecting driving pins 6, 8 and 8 may be secured, hence by removing any one ot the pins from one hole, and changing it to another hole, the combination ol the lock will be changed. Each tumbler is also provided with a spring pressed pin 1Q, seated in a recess in the periphery ot the tumbler, and adapted to engage the inner wall ot the cylinder or casing 1, and bear thereagainst with suflicient friction to prevent any accidental movement of either tumbler'. The tumblers 7 and 9 are as before explained, located within the cylinder 1 in rear ot the dial 4, and are turned or rotated by the latter.

Mounted within, and passing through the dial, tumblers and rear end ot' the cylinder or casing 1. is the sleeve 3, the front end 1? of which is cylindrical in shape and of greater diameter than the cylindrical rear portion 14. The extreme rear end 15 oi' the sleeve is still further reduced in diameter and is externally threaded to be engaged by the nut 1G, which latter bears against the rear wall of the cylinder or casing 1 and locks all the parts above referred to against withdrawal from the cylinder. The cylindrical portion 13 ol the sleeve, has a snug fit within the bore o1 the dial. while the cylindrical portion l-l ot' said sleeve snugly fits within the ring shaped tumblers 7 and 9. This cylindrical portion 14 ot' the sleeve 3 is provided with a series of holes -for the locking pin 3, the holes being so located that one pin will be in alinemcnt, with the rear end of the dial, andl the others are in alineinent with the tumblers 7 and 9 respectively.

Passing through the sleeve 3, is the spindle 17, provided at its outer end with a knob 17 by which it is turned, and at its inner end, at the rear of the sleeve, with a stein 1S, which is designed for connection by suitable mechanism with the bolt locking and releasing device. This spindle is provided with a peripheral slot 19 into which the screw 20 carried by the sleeve 3 projects, thus locking the spindle 17 in place against endwise displacement, and the head oli this screw 2O resting within the slot Q1 in the rear wall ot the cylinder or casing 1, prevents the sleeve from rotating. The spindle is also provided with a cani shaped body 22, against which the ends of the locking pins 3 rest. Vhen this cam 22 is turned so that its tlat face is immediately under and is supporting the locking pins 3a, the latter' will be wholly within the sleeve 3, but when the cam 22 is turned so that its curved face is in contact with the locking pins, the latter will be projected into the gatings in the dial l and tumblers 7 and 9.

Normally when the door is locked, the locking outwardly by their contact with the inner surfaces of the tumblers, and the inner ends of the locking pins, being in contact with the fiat face of the cam, positively lock the spindle against rotation.

The dial rotates the two tumblers, and when the dial is rotated in the` usual inanner to bring the gatings 10 in the tumblers 7 and 9 into alinement with the locking pins 3a, thus releasing the latter, the spindle 17 will then be free to be turned by hand to actuate the bolt locking and releasing mechanism. The normal position of the flat surface of the cam 22 when the bolts are locked or unlocked is adjacent the locking pins, hence by giving the dial a turn, the gatings in one or both of the tumblers 7 and 9 will be carried out of alinement with its locking pins 3a, thus preventing the latter from being projected, hence before the spindle can be turned, the dial must be actuated to bring all the tumblers into position where their gatings will aline with the locking pins so that the latter may be moved by the cam, and as before stated the combinations may be changed by simply changing the positions of any one of the driving pins.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence 1 would have it understood that l do not wish to confine myself to the exact construction and arrangement of parts shown and described, but

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. In a combination lock, the combination with a casing, a dial carried by said casing, and tumblers within and carried by the casing and actuated by the dial, of a spindle passing through the casing, dial and tumblers and mounted to rotate in the same, and longitudinally movable locking pins, interposed between the tumblers and spindle and bearing against both for locking the spindle against rotation.

2. ln a combination lock, the combination with a casing, a dial having a driving` pin, and ring shaped tumblers each having a driving pin, and each also provided on its inner side with a gating, of a spindle and a series of longitudinally movable locking pins interposed between the tumblers and spindle for locking the latter against rotation.

0' pins are prevented from moving 3. The combination with a casing, a dial, and a plurality of ring shaped tumblers, each of the latter having an internal gating and a friction device for preventing its accidental rotation, of a rotating spindle and means interposed between said spindle and tumblers for locking the former against rotation, except when the tumblers are moved to bring their gatings into alinement with said locking means.

4L. The combination with a casing, a sleeve therein and a dial and tumblers mounted on the sleeve within the casing, each tumbler having a gat-ing on its inner side, of a spindle within the sleeve and a series of locking vpins carried by the sleeve and bearing `secured therein and a dial and tumblers mounted to rotate on the sleeve, each tumbler having a gating in its inner wall, of a spindle mounted in the sleeve and provided with a cam shaped section and a series of locking pins mounted in the sleeve and bear` ing at one end against the tumblers and at the other end on said cam shaped section.

G. The combination with a casing, a sleeve secured therein, and a dial and a series of tumblers mounted within the casing and on the sleeve, of a spindle mounted in the sleeve and provided with a cam shaped section and a plurality of locking pins seated in holes in the sleeve, one of said pins bearing at one end against the dial and at its other end against the cam shaped section of the spindle, and the others, each bearing at one end against a tumbler and at its other end against said cam shaped section, the said dial and tumblers having gatings in which the pins enter when the parts are properly manipulated to release the spindle.

7. The combination with a casing, of a dial therein, a series of ring shaped tumblers each having a gating in its inner face, and each having a removable and adjustable driving pin, a spindle axially mounted in the dial and tumblers, and provided with a cam shaped surface, and a plurality of loclring pins interposed between the cam section of the spindle and the t-umblers for locking the spindle against rotation except when the gatings in the tumblers are in alinement with the pins.

In testimony whereof, l have signed this speciiication in the presence of two subscribing witnesses.
